Exploration-Exploitation Model of Moth-Inspired Olfactory Navigation
Teddy Lazebnik, Yiftach Golov, Roi Gurka +2
Navigation of male moths toward females during the mating search offers a unique perspective on the exploration-exploitation (EE) model in decision-making. This study uses the EE m…
OpenPIV-Matlab -- An open-source software for particle image velocimetry; test case: birds' aerodynamics
Hadar Ben Gida, Roi Gurka, Alex Liberzon
We present an open-source MATLAB package, entitled OpenPIV-Matlab, for analyzing particle image velocimetry (PIV) data. We extend the PIV analysis with additional tools for post-pr…
Unique flow features of the silent southern Boobook owl wake during flapping flight
Jonathan Lawley, Hadar Ben-Gida, Krishnan Krishnamoorthy +5
The mechanisms associated with an owls ability to fly silently have been the subject of scientific interest for many decades and a source of inspiration in the context of reducing…
Experimental study of the initial growth of a localized turbulent patch in a stably stratified fluid
Lilly Verso, Maarten van Reeuwijk, Roi Gurka +3
We present a laboratory experiment of the growth of a turbulent patch in a stably stratified fluid, due to a localized source of turbulence, generated by an oscillating grid. Synch…
Scales of influence on the settling velocities of synthetic, industrial and natural particles in grid turbulence
Corrine Jacobs, Wilmot Merchant, Marek Jendrassak +3
The settling velocities of natural, synthetic, and industrial particles were measured in a grid turbulence facility using optical measurement techniques. Particle Image Velocimetry…
Stratified wake of an accelerating hydrofoil
Hadar Ben-Gida, Alex Liberzon, Roi Gurka
Wakes of towed and self-propelled bodies in stratified fluids are significantly different from non-stratified wakes. Long time effects of stratification on the development of the w…
On the estimation of time dependent lift of a European Starling during flapping
Oksana Stalnov, Hadar Ben-Gida, Adam J. Kirchhefer +4
We study the role of unsteady lift in the context of flapping wings in birds' flight. Both aerodynamicists and biologists attempt to address this subject, yet it seems that the con…
Moth-inspired navigation algorithm in a turbulent odor plume from a pulsating source
Alex Liberzon, Kyra Harrington, Nimrod Daniel +3
Some female moths attract male moths by emitting series of pulses of pheromone filaments propagating downwind. The turbulent nature of the wind creates a complex flow environment,…
Estimation of unsteady aerodynamics in the wake of a freely flying European starling
Hadar Ben-Gida, Adam Kirchhefer, Zachary J. Taylor +4
Wing flapping is one of the most widespread propulsion methods found in nature; however, the current understanding of the aerodynamics in bird wakes is incomplete. The role of the…
Experiments on the vortex wake of a swimming knifefish
Zachary J. Taylor, Alexander Liberzon, Roi Gurka +3
The knifefish species propels itself by generating a reverse Karman street from an anal fin and without significantly moving its body. This unique feature makes this species' propu…
Turbulent flow over a house in a simulated hurricane boundary layer
Zachary Taylor, Murray Morrison, Roi Gurka +1
Every year hurricanes and other extreme wind storms cause billions of dollars in damage worldwide. For residential construction, such failures are usually associated with roofs, wh…
